Datavideo DVK-400

The Datavideo DVK‑400 is a professional broadcast-grade 4K chromakey processor designed to deliver exceptional real-time keying performance for virtual studios, live productions and advanced broadcast applications. Built around a powerful 4:4:4 10-bit image processing engine, the DVK‑400 supports resolutions up to UHD 2160p60, providing highly accurate colour separation, smooth edge transitions and outstanding image quality for demanding production environments.

Engineered for professional virtual production workflows, the DVK‑400 excels at handling challenging chromakey scenarios that often prove difficult for conventional keyers. Fine details such as blonde hair, transparent objects, glass surfaces, smoke and reflections can be reproduced with remarkable accuracy, resulting in clean and natural composites that enhance the realism of virtual environments.

Advanced keying controls include spill correction, edge correction, key masking, colour processing and noise reduction, providing operators with precise control over every aspect of the compositing process. These tools allow foreground subjects to be blended seamlessly into virtual sets while preserving subtle details and maintaining a natural appearance.

To simplify operation, the DVK‑400 features an intelligent Auto Key function that automatically generates professional chromakey results with minimal setup. This allows operators to achieve high-quality keying quickly, making the system suitable for both experienced broadcast engineers and users who require fast deployment in live production environments.

For HD productions, the DVK‑400 also offers a background blur function that can create a shallow depth-of-field effect, helping subjects stand out naturally from virtual backgrounds and giving productions a more cinematic appearance.

The processor is controlled via Datavideo’s dedicated Windows-based software over an Ethernet connection. Users can fine-tune settings, save custom configurations and instantly recall stored presets, allowing rapid switching between different studio environments and production requirements. With support for multiple user presets, recurring productions can be set up in seconds.

Professional connectivity includes 12G‑SDI and HDMI 2.0 inputs and outputs, dedicated preview and program outputs, loop-through functionality, auxiliary inputs and reference synchronization support. These extensive connectivity options enable seamless integration into modern UHD broadcast infrastructures, virtual studios and live production facilities.

Housed in a compact 1RU rackmount chassis, the DVK‑400 is designed for reliable operation in professional studio environments. Combining true 4K processing, advanced chromakey controls and broadcast-quality image precision, it provides a powerful and accessible solution for creating immersive virtual productions and high-end live broadcasts.
